The lack of atrophy is a virtue of online gaming’s illusion of permanence. While enemies may respawn in a few seconds, the ratchet only goes one way on character and story advancement. You need not hit the gym to keep your points in strength from fading. Your house never gets dirty, and maintenance of everything you own is streamlined to a few clicks. You can wear the same clothes continuously for months, and you never need to iron the cloth armor in your vault. Your armor is always shiny and your sword is always on fire. Cooking and eating are optional, and the thousand stuffed cabbages in your backpack never rot.
Monsters and dungeons more closely resemble your floors and bathrooms. You can clean them out entirely, but you’ll need to do it again the next time you look.
